low. The fitting of-intercha-ngeable boxes for spraying material on, inor below the running platform step is often not desirable o'nprivate-cars, onaccount of unpleasing appearance. Notwithstanding theurgent I necessity to fit motor cars with sand spraying devices nothinghas been done up to the pres-' ent time owing to the difficulty ofaccommodating the devices on the cars. The disadvantages hithertoexisting are 29 overcome according to the invention, in that themudguards of the car are provided With double walls, forming containersfor the spraying material. Consequently these latter are absolutelyinvisible, do not take up any room and a considerable drop for thespraying material is obtained.

An embodiment of the invention is illustrated' by way of ezsample in theaccompanyingadrawings in which:

removably flanged on the container. On removing the mouthpiece f, theaperture produced is closed by a cover. The mouthpiece is slightlytapered towards its lower end to form a slot opening 9, in which theelement for regulating the discharge of the spraying material isarranged. -This element may bea register, flap or rotatable shaft h, asshown, which is provided with a discharge slot z and through the settingof which the discharge is closed or more orless opened. The mouthpiece.f may also terminate at the lower end into one or' more nozzles, whichare then maintained in open or closed condition by means of resilientflaps. The adjustment of the element regulating the discharge of thespraying material, for example of the shaft h, is effected from thedrivers seat by any suitable distant control, such as rod system or.Bowden cable, which act upon a double lever m, n of the shaft h. Inorder to reliably bring the spraying material to in front of the wheelin question, an elastic guiding element 0, made of leather or rubber,extends from the mouthpiece f.

I claim: A sand spraying device for motor vehicles, especially for motorcars adapted to be operated from the drivers seat, comprising incombinationthe mudguards of the car wheels having a double wall ada tedto formachute for the spraying materia a charging flap on the upper partof the outer one of said walls, and a mouthpiecedetachably flanged onthe lower end of said chute adapted to regulate the discharge of thespraying material.

In testimony whereof I affix my-signature.
